Joe,
There's a new book just out entitled "Exploring Analytic Geometry with
Mathematica" (Academic Press, ISBN: 0127282556, Vossler). It includes
software for drawing ellipses (and other conics) at angles, plus a lot more.
You can find it at both www.amazon.com and www.barnesandnobel.com.
I am the author of the book, and would welcome any comments you might have
on it (the entire book and software packages are provided as Mathematica
notebooks on the CD-ROM that is provided with the printed version of the
book).
